Yolk syncytial layer nuclei undergo epiboly and converge dorsally during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

Yolk syncytial layer cell nuclei exhibit convergence and extension behaviors during late gastrulation. Video made available by Mark Cooper through Zebrafish - The Living Laboratory.

Morphogenesis of the ventral yolk syncytial layer (YSL) from sphere stage to the end of gastrulation. The last round of nuclear division occurs before marginal band contraction and epiboly begins. As ...

Timelapse of yolk syncytial layer (YSL) nuclear movements during gastrulation from a dorsal-anterior view shows epiboly, early animal pole directed movements of I-YSL nuclei, and convergence and exten...
